SolrCloud（集群，基于zookeeper集群）的搭建与使用

阅读更多关于 SolrCloud（集群，基于zookeeper集群）的搭建与使用

SolrCloud简介 SolrCloud(solr 云)是Solr提供的分布式搜索方案，当你需要大规模，容错，分布式索引和检索能力时使用 SolrCloud。当一个系统的索引数据量少的时候是不需要使用SolrCloud的，当索引量很大，搜索请求并发很高，这时需要使用SolrCloud来满足这些需求。 SolrCloud是基于Solr和Zookeeper的分布式搜索方案，它的主要思想是使用Zookeeper作为集群的配置信息中心。它有几个特色功能： 1）集中式的配置信息 2）自动容错 3）近实时搜索 4）查询时自动负载均衡 Solr集群的系统架构 1.1. 物理结构三个 Solr 实例（每个实例包括两个 Core ），组成一个 SolrCloud 。 1.2. 逻辑结构索引集合包括两个 Shard （ shard1 和 shard2 ）， shard1 和 shard2 分别由三个 Core 组成，其中一个 Leader 两个 Replication ， Leader 是由 zookeeper 选举产生， zookeeper 控制每个 shard 上三个 Core 的索引数据一致，解决高可用问题。用户发起索引请求分别从 shard1 和 shard2 上获取，解决高并发问题。 1.2.1. collection Collection 在 SolrCloud

Zookeeper starts sucessfully - the goal is to do a distributed search across the different collections.

So I cannot update collections 2 & 3 as they are missing their correct fields. I have tried each of the
